Proxmox Cluster Setup

Setting up a Proxmox VE cluster allows you to manage multiple Proxmox nodes from a single interface, enable high availability (HA), and prepare your homelab for live migrations and centralized backups.

🧱 Requirements​

  • 🖥️ 2 or more Proxmox VE nodes
  • 🧠 Unique hostnames and static IPs for each node
  • 🌐 Proper DNS or /etc/hosts entries across all nodes
  • 🔐 Root SSH access between nodes
  • ⛔ No existing cluster (nodes must be standalone)

🧰 Step 1: Prepare Each Node​

Ensure hostname and network configuration is consistent and unique:

hostnamectl set-hostname proxmox-node1
